Abstract
It is an object to prevent a poor X-ray CT image due to scattered X-rays. An X-ray CT scanner () uses an X-ray detector (), etc., to scan (F) an object () to obtain X-ray transmission image data, and estimate (F) an X-ray absorption coefficient distribution inside the object () based on the scanned X-ray transmission image data. Next, the X-ray CT scanner () performs a Monte Carlo simulation on a simulated object () having the X-ray absorption coefficient distribution estimated, and estimates (Fand F) a point spread function or scattered X-ray distribution derived from the object. Then, the X-ray CT scanner () corrects (Fand F), based on the point spread function or scattered X-ray distribution estimated, the X-ray transmission image data, and finally creates (Fand F) an image of the X-ray absorption coefficient distribution of the object ().
